This Article shall be known as the "Andover
Borough Driveway Ordinance."
The purpose of this Article is to control the
access to lots and parcels of land lying in the borough and to assure
that any access provided to such lots or parcels of land meets the
minimum requirements hereinafter set forth and assures safe ingress
and egress to such property.
The following definitions shall apply in the
interpretation and enforcement of this Article:
ALTERED
Any existing point of access where the present sight distance
has been reduced more than 10% or the grade within the first 25 feet
from the intersecting road has been altered more than 10%.
DITCHES AND DRAINAGEWAYS
Any stream, watercourse, pond, swale, swamp, depression or
ditch that must be crossed in connection with the construction of
a driveway.
DRIVEWAY
Any point of access to a lot or parcel of land adjacent to
any public road used for other than purely pedestrian access.
All driveways shall be constructed or altered
in accordance with the following minimum requirements:
A. Permitted driveways. The number of driveways permitted
from any lot to any abutting road shall be in accordance with the
following standards, except where conditions of safety of the general
motoring public may be impaired:
(1) Single-family residence zones. When a circular driveway
is desired, two driveway openings may be constructed.

(2) All other zone districts. In determining the number
of driveways to be permitted in all other zone districts, the requirements
for development set forth in the Zoning Chapter shall be considered
as minimum requirements, and at the time of site plan review, proposed
driveway locations shall be reviewed in accordance with the site plan
review standards, taking into consideration, to be supplied by the applicant,
the county standards for access to county roads.
B. Sight distances required. Any exit driveway shall
be designed in profile, grading and location to permit the following
minimum sight distances measured in each direction along the intersecting
roads. The measurement shall be from the driver's seat of a vehicle
standing on that portion of the exit driveway with the front of the
vehicle a minimum of three feet behind the curbline or the edge of
the shoulder of the intersection road, and the height of the eye of
3 3/4 feet to the top of an object 4 1/2 feet above the
road surface.

C. Angle of intersection. All driveways constructed or
altered within 50 feet of the center line of the road shall intersect
the abutting road at an angle as near to 90° as sight conditions
will permit but in no case less than 70°.
The following design standards shall be applied to all driveways requiring a permit, in accordance with §
117-8:
A. Emergency vehicle access. To assure access for emergency
vehicles, the driveway shall contain no curvature with less than a
fifty-foot radius, and the driveway crown shall be relatively flat
to prevent dragging of any vehicle undercarriage. Reasonable cutting
and filling may be used to achieve compliance with the above requirements.
B. Width. All driveways constructed or modified shall
have a minimum driving width of 10 feet and an entrance not greater
than 20 feet in width, unless otherwise permitted by the governing
body.
C. Erosion. All driveways shall be constructed in such
a manner that land areas abutting the driveway surface, and the driveway
surface, shall be stabilized to prevent erosion. All driveways shall
be designed so that surface water shall not be directed onto the abutting
road, and necessary steps shall be taken to prevent siltation of road
gutters, catch basins and cross drains. All driveways shall be maintained
in such condition that their surface and adjacent areas are stabilized
to prevent erosion. The following is therefore required for driveways
ascending from the roadway:
(1) A section with four-to-six-percent grade sloping down
and away from the existing road and extending four feet from the edge
of the road.
(2) An additional eight-foot-long section with a maximum
grade of 8%.
(3) A maximum grade of 15% for the remainder of the driveway.
D. Ditches and drainageways. All driveways shall be designed
and constructed so that existing drainage ditches and drainageways
are not obstructed. Where necessary to provide or maintain free flow,
which cannot be maintained with a shallow dish gutter, a reinforced
concrete pipe, having a minimum diameter of 15 inches, shall be installed
in the ditch or drainageway.
E. Intersection with abutting road. At the point of intersection
with the abutting road, the driveway shall provide an even surface
with the traveled way or shoulder and shall not extend into the traveled
way or shoulder in such a manner as to cause a sharp increase or decrease
in elevation, thereby creating an uneven driving surface.
F. Intersecting roads. When a site from which a proposed
driveway exits occupies a corner of two intersecting roads, no driveway
entrance or exit shall be located within 25 feet of the point of tangency
of the existing or proposed curb radius of that site.
G. Construction material. For a minimum distance of 10
feet from the improved portion or shoulder of the public road, all
driveways shall be constructed of the following material:
(1) Driveways entering unpaved roads shall be four inches
compacted thickness of dense graded aggregate thoroughly rolled and
compacted of the specified width.
(2) Driveways entering paved roads shall have a base course
of four inches compacted thickness of dense graded aggregate thoroughly
rolled and compacted and a surface course of two inches compacted
thickness of bituminous concrete Type A or Type FABC-1.
H. Stabilizing of certain slopes. All banks exceeding
six feet in height shall have crown vetch or some other stabilizing
material planted. Side slopes shall not exceed two to one.
I. Side lines of driveway to be marked. The side lines
of the proposed driveway shall be identified by stakes placed 10 feet
from the edge of the road and thence at twenty-five-foot intervals
along the driveway.
J. Where a site occupies a corner of two intersecting
roads, no driveway shall be located within 25 feet of the point of
tangency of the existing or proposed right-of-way return of that site.
